Guillaume Cale

Guillaume Cale (sometimes anglicized to William Kale, also known as Guillaume Caillet, popularly known as Jacques Bonhomme ("Jack Goodfellow") or Callet) was a wealthy peasant from the village of Mello near Beauvais, who became leader of the peasant Jacquerie which broke out in May 1358 and continued for a month unchecked until the Battle of Mello on 10 June. Cale's origins are unknown, it is not clear how old he was at the time of the uprising, nor is anything known about his family and business ties, except that he was a reasonably well-off farmer.
